The movable plate is pulled so that the adjustment rod slides to the outermost position on the side of the connecting rod. The block slides inside the movable groove under the guidance of its own taper to squeeze the first spring to deform, and the synchronous movable rod is separated from the groove. The position of the movable rod is adjusted to be clamped in the slot at a suitable position. After the position adjustment is completed, the LCD panel is placed between the clamping rods. When the movable plate is moved to squeeze the LCD panel to the side position of the support plate, the extrusion rod is reset so that the cooperation rod limits the movable rod. At the same time, the block is reset and clamped in the position inside the slot under the deformation force of the first spring. In this way, the LCD panel can be placed outside the machine for operation, which is convenient for loading and unloading. The position of the clamping rod can be adjusted by tools to adapt to LCD panels of different specifications.

[0016] (2) The LCD panel coating equipment, through the coordination of the internal components of the clamping mechanism, drives the ring to engage and rotate, the slide is rotated and guided inside the slide slot, and the mounting frame rotates accordingly so that the fourth gear engages with the first gear, the fourth gear drives the third gear to rotate, the third gear drives the second gear to rotate through the conveyor belt so that the mounting rod rotates, the mounting rod drives the matching plate to rotate, and another set of matching plates rotates in coordination on the side of the second gear, so that the fixed block rotates while the whole body revolves, so that the matching plate maintains a vertical angle position when in the unloading station, which is convenient for workers to operate.
